Across the span of Carl F. Gould's career in Seattle (1908-1939), architectural design moved from eclectic adaptations of historical models to the adoption of regional and nontraditional styles espoused by the Modern movement, and his buildings fully reflect this range of expression. Gould's design for the Seattle Art Museum was the first art museum in the country to be built in the modern style. His design development drawings for the museum are unique among those in the Gould collection for their precise dating. They reveal the design sequence from his earliest neoclassical efforts to his final modern solution. Interior gallery and public spaces were emphasized by use of colored natural materials in red, green and black, accented by gold and aluminum. The two elongated galleries along the east side had windows overlooking the park at the back of the museum. The central "garden court" contained a green fountain and plants covered by a flat-roofed skylight. The lower level housed administrative spaces, library and auditorium. A daylight basement level provided additional office space, a workshop, facilities, delivery area and art storage. As they were needed office and exhibition space were added to the rear of the building in subsequent decades, although these additions did not conform to the original expansion plans developed by Bebb & Gould. (Although Bebb remained Gould's partner and business adviser until the latter's death, after 1924 his influence in the firm declined substantially.) In 1991 a new museum was built in the downtown area and the Volunteer Park building became the Seattle Asian Art Museum.
